| 摘 要： | 现代风力发电的发展,对风电生产提出了新的需求,即在电网电压跌落处于一定范围内时风力发电机装置必须保持和电网相连。研究了在电网电压跌落发生期间和故障清除后,双馈感应式风力发电机（DFIG）的转速,直流侧电压,有功,无功等量的动态响应,并分析了响应产生的机理。利用matlab/simulink建立了DFIG的仿真模型,并介绍了相应的控制方法,而DFIG模型在电网电压跌落下的仿真结果则很好地验证了分析所得结论的正确性。

| Abstract: | With the development of modern wind energy generation, new requirement on the generation was raised, that was the turbines should stay connected to the grid in case of a failure. Transient analysis was given including speed, DC link voltage, active and reactive power of the variable speed wind turbines with doubly fed induction generator (DFIG) both during the grid voltage dip and after the clearance of the fault. A DFIG model was proposed under matlab/simulink as well as a detailed control scheme. The simulation results under a grid voltage dip have validated the analysis conclusion. |
